Mouth ulcers concerns

Mouth ulcers are painful sores that appear in the mouth, usually on the soft tissue - cheeks, lips or tongue. They can be white, red, yellow or grey in colour and swollen.

Although they're uncomfortable, mouth ulcers are usually harmless and clear up by themselves within a week or two.

In many cases, the reason for mouth ulcers is unclear, but triggers are thought to include:

  • Accidentally biting the inside of your cheek or a sharp tooth
  • Poorly fitting dentures
  • Hard food
  • A defective filling
  • Stress and anxiety
  • Hormonal changes – some women develop mouth ulcers during their monthly period
  • Eating certain foods – such as chocolate, spicy foods, coffee, peanuts, almonds, strawberries, cheese, tomatoes and wheat flour
  • Toothpaste containing sodium lauryl sulphate
  • Stopping smoking – when you first stop smoking, you may develop mouth ulcers
  • Viral infections – including the cold sore virus, chickenpox, and hand, foot and mouth disease
  • Medical conditions - including vitamin B12 or iron deficiency, Crohn's disease, coeliac disease, reactive arthritis, HIV, lupus, Behçet’s disease
  • Certain medications or medical treatments may also cause mouth ulcers

It's usually safe to treat mouth ulcers at home to help reduce swelling and ease any discomfort.

Self care

Tips for easing discomfort and aid healin…

  • Antimicrobial mouthwash or protective paste, available from your pharmacist
  • Use a soft toothbrush to brush your teeth
  • Use a toothpaste that doesn’t contain sodium lauryl sulphate, as this may be irritating
  • Avoid hard, spicy, salty, acidic or hot food and drink until the ulcer heals
  • Use a straw to drink cool drinks
  • Avoid things that may be triggering your mouth ulcers

Mouth ulcers can sometimes be a possible symptom of a more serious problem such as infection or mouth cancer. It's therefore essential that you contact [practice name] as soon as possible if you notice:

  • your mouth ulcer becomes more painful or red

Another great experience at Mortiboys Dental Spa this morning for hygiene and a checkup. The staff are courteous, kind, patient and very friendly. As a nervous patient, I always appreciate their special care. I can’t recommend this beautiful dental spa highly enough. It really is a five star service.

I can’t speak highly enough of Clare who is my dental hygienist. From the moment you sit in her chair, she brings a rare combination of professionalism, warmth, and genuine care that immediately puts you at ease. She has an exceptional attention to detail and takes the time to explain everything clearly, making sure you feel informed and comfortable throughout the entire appointment.

I received excellent care from both the dentist and the hygienist and it was very good value for money. They listened to any issues I had and gave advice on how to maintain my teeth at a high standard of cleanliness until the next appointment.
